WRINGER.

Application filed December 29, 1921. Serial No. 525,647.

To all whom it may concern Be it known that l, GEORGE R. KELTIE, a

`citizen of the United States, residing at Woonsocket, in the. county of Providence and State of Rhode Island, .have invented certain. new and useful Improvements in the employment of a `minimum number of parts auxiliary: to the standard wringer structure; the avoidance of the use of jointed or sectional bars for releasing purposes whereby the structure is weakened; and the attainment of these results in a simple, self contained, and inexpensive structure.

Other objects and advantages of the invention will be apparent as it is better un-4 derstood from the following description when considered in connection ywith the accompanying drawings illustrating a preferred embodiment thereof.

To the above ends primarily my invention consists in such parts and in such combinations of parts as fall within the scope of the ap ended claims. l

n the accompanying drawing whic forms a part of this specification,

Figures 1 and 2 are a front and side elevation respectively of a Wringer embodying my invention,

Figure 3, asection of the same on line 3-3 of Figure 1, in locked position,

Figure 4, a fragmentary section on line 3 3, in released position,

Figures 5 and 6, longitudinal central sections of the wringer in locked and released positions respectively,

i Fi re 7 a horizontal section on line 7--7 of Flgure 5, and

Figure 8, a plan view of a reclining spring.

Like reference 4characters indicate like parts throughout ythe views. v

In the construction illustrated the frame comprises side bars 11 provided with the usual guide slots 12 and vertical grooves 13;

a top or crossbar 15 in which are incor porated in this instance threaded bushings 16 for the pressure screws 17 housing strips 19 fast to the side bars; bars 22 also fast to the side lbars having clothes guide shouldered portions 23; and a drain plate orl apron 25 pivoted by pins 27, carried by the side bars, extending into oblong bayonet slots 29. Buttons 31 pivoted to the bars 22 clamp the apron in inalposition.

In this instance a housing 35 fast to one of the side bars covers the gearing; and an gular reinforcing plates 37 fast to -the side bars and overlapping the ends of the top bar are employed. The latter are perforated as at 39 to admit the presser screws.

Lower and upper pressure rolls 41 and 42 have their respective Shafts 43 and 44 extending through the slots 12in the side bars, and respectively carry the intermeshing gears 46 and 47 driven by the main shaft 43 inany usual convenient manner. The latter shaft rests on bearing blocks49 in the lower ends of the` slots 12, while thev driven shaft 44 has resting thereon bearing blocks 51, In this instance' guard plates 53 fast in the end bars by screws 54 have inwardly di'lected flanges 56 enclosing the ends of the ro s.

Fast to the top of each of the superposed bearings 51'by screws 58 or otherwise is a hinge plate 5 9 having upon its inner 4edge hinge sleeves carrymg a pintle 61 in hinge sleeves 62 .on the corresponding edge of a hinge plate 64 integral with or fast to a pressure spring 66. Integral with or fast to the upper end of each spring is a cam block 68 having upon itsupper part an outwardly and downwardly directed inclined cam face 69 engageable with the end of the adjacent pressure screw 17. The descent of the screw upon the cam face 69 combines with the stored 'up energy of the spring tov impel the cam inwardly.

he impulsion of the cams 68 is normally checked by the following device.

A rock 'shaft 71 is supported in metal straps 72 fast by screws' 7 3v or otherwise to the crossbar 15. Upon the ends of the bar are fingers 75 disposed at rightl angles thereto and parallel with each other. The central portion of the rock shaft vhasa depending loop or double crank 77. A. handle for the crank in this instance comprises an open or incomplete ring 79 loosely surrounding the crossbar 15 and provided with lateral ears or anges 81 upon its ends. The ring at a point opposite its open portiom'isffast to the'crank 77 by rivets 84 or otherwise; vNor'- A mally theingers abut against he inner faces ofthel cams 68. Thepmanli' nbt'ation A zontal slot or opening 29 terminating at both Aends in extensions thereofor recesses 85 disposed at right angles thereto. It Will be 'observed that when a pin 2T registers in one' ofthe recesses 85 the drain plate is locked against the movement of the latter in the direction of its inclination".v

It is to be understood that the invention is :not limited to the specific form herein illusllowing the springs'to move on their pivots trated and described, but may be embodied in other forms without departure from its spiritas defined by the following claims.

I claimz l. Ina wringer, pressure rolls, bearings slidably supported by the rolls, tiltable compression springs pivotally supported on the vbearlngs, cams on the springs, screws 1n alignment with the springs and engaging the earns" for compressing thev "springs, A, and

means engageable with t-he ca'mslfor nor-v mally retaining them inoperative position and ope-rable't'or releasing the cams and al- -into a horizontal position.-

2. In a'wringenrolls' bearings supported thereby, plates on the bearings, plates on the first plates, hinges connecting the first and second plates, springs upon the second plates', cams fast to the springs, means engaging the cams for compressing the springs and laiding to force them to suddenly move on their pivotswvhen released, `and auxiliary means engaging the camsl for maintaining the springs against such movement. A

3. In a Wringer, rolls, slidable bearings therefor, vertically disposed springs pivotally connected with thebearings and supported' thereby, cams on the springs, pressure screws engaging t-he tops ,of the cams, a rockv shaft, fingers on the shaft engaging the sides of the cams, and'means for operating the rock shaft. l

4.In a Wringer, rolls, slidable bearings thereon, springs supported on the bearings, cams on the tops of the springs, pressure screws engaging the top faces of the cams, a

i rock shaft,` fingers on the shaft engageable with the cams, a. crank on the shaft, and an operating arm on the crank.

5. In a. Wringer,'rolls, bearings thereon, springs supported by saidbearings, cams affixed to said springs, pressure screws bearing on said cams, and retainin means for said springs and cams releasab ea to permit sudden vmovement of the'oams and springs out of complete engagement with i' saidC p screws.

6. In a Wringer, rolls, bearings thereon, springs pivotally supported by 'said bearings for bodily movement toward each` other Whennot restrained, cams having outwardly vvinclined surfaces, pressure screws bearing on sald cams, and retaln-mg means fornholding said cams and springs in operative position and releasable to permit the springs to suddenlymove toward each other out of complete, engagement Wlth sald screws.

f In' testimony-whereof' I have affixed my signature. I
